In the documentation for `float-time' in "(elisp) Time of Day" I read
the following: "_Warning_: Since the result is floating point, it may
not be exact. Do not use this function if precise time stamps are
required."
Okay, so what do I use instead? I just want a "UNIX timestamp" as an
integer or string. What's the idiomatic way to get that?
